The handle_xfercomp_isoc_split_in() use two conditions
to check if the isoc in csplit transcation is done:
- the actual xfer length of the current frame is zero
- the total xfer length of the frames equals to the
request length of the frames
But in some case, we find that the two conditions are
not enough, e.g. on rockchip platforms, connect the usb
audio card with the FE1.1 HUB, the audio is setted to
44100 2ch 16 bits, the csplit transcation sequence is:
- CSPLIT IN transcation
- MDATA packet [176 bytes]
- CSPLIT IN transcation
- DATA0 packet [No data]
In this case, the total actual xfer length of frames is
less than the request length of frames, so the current
code will not update the status of frame and the qtd
isoc_frame_index, this cause usb audio data corrupted.
According to the USB 2.0 spec "Figure 11-85. Isochronous
IN Complete-split Transaction Sequence", we can use DATA0
to check if the transaction is last data. So use DATA0
instead of zero length transaction to check if the csplit
transcation is done.

According to DWC2 Programming Guide, if a host channel is
used for non-split periodic transfer, we must not disable
the channel if we want to halt it, and at the end of the
next uframe/frame (in the worst case), the core generates
a channel halted and disables the channel automatically.
But some specil usb device, like usb audio (VID = 0x0572,
PID = 0x1494, Manufacturer: Conexant Systems INC), we
need to halt the channel immediately when do close usb
audio operation. Otherwise, the host may still start a
new transaction after usb audio close, and cause to set
usb interface failed when open usb audio next time.
This patch introduces a new quirk to force host channel
halt even if it's used for a non-split periodic transfer.

The dwc2 programming guide section 3.5 'Halting a Channel'
says that the application can disable any channel by
programming the HCCHARn register with the HCCHARn.ChDis
and HCCHARn.ChEna bits set to 1'b1. This enables the
dwc_otg host to flush the posted requests (if any) and
generates a Channel Halted interrupt.
But it also requires that channel disable must not be
programmed for non-split periodic channels. At the end
of the next uframe/frame (in the worst case), the core
generates a channel halted and disables the channel
automatically.
If we disable non-spilt periodic channels to halt the
channels, it will easily to cause data transfer fail.
A typical case is take photo with usb camera or close
usb camera, Specifically, the observed order is:
1. uvc driver calls usb_kill_urb
2. usb_kill_urb calls urb_dequeue to cancel urb
3. urb_dequeue call dwc_otg_hc_halt to disable
non-spilt periodic channels
4. usb core doesn't halt the non-spilt periodic
channels immediately, and the application
reallocates the channels for other transactions
without waiting for the HCINTn.ChHltd interrupt.
5. uvc driver calls usb_set_interface to start
control transfer, and gets a channel which used
for non-spilt periodic transfer before. The core
generates a channel halted and disables the channel
automatically. This cause control transfer fail.

When dequeue a transfer request, dwc_otg_310 pcd driver
will call dwc_otg_pcd_ep_stop_transfer() function, it
set the whole depctl register value to 0. But actually
it should only set nak and disable ep, and do not change
ep type or mps information and so on, because these information
should only be setted by ep_enable() or ep_disable() functions.
If clear the whole depctl register in dwc_otg_pcd_ep_stop_transfer,
it will cause the current transfer failed during dequeue.

to dwc_otg_databook_v3.10, this interrupt is valid only for
control OUT endpoints, it indicates to the application that
the host has switched from data phase to the status phase
of a control write transfer. The application can use this
interrupt to ACK or STALL the Status phase.
We use v3.10a dwc2 on rockchip soc, but actually we don't
need to send Zero-Length Packet for the IN status phase
